The subject has a very slow load

I’ve read your documentation advice to improve the speed of the web, but as he had done previously. My score measurement tool loading speed is only 37/100 and is due to the weight of the theme (otherwise very happy with it).
The sites are http://garpopeluqueriasanxenxo.es/ and http://ferroferreteria.com/ please take a look and tell me if I can disable any plugin or some functionality of your template to improve loading speed.

thanks
